Flexible Flange Adaptor

A flexible flange adaptor, also known as a flexible pipe coupling or flange coupling, is an essential component in plumbing and pipeline systems. It serves the purpose of connecting two pipes or pipe fittings with flanged ends, allowing for the efficient transfer of fluids while accommodating for minor misalignments or movement between the connected pipes. The key components of a flexible flange adaptor include two flanged ends, a flexible or rubber element, and bolts with nuts.
